Everyone is so angry at Michael Moore because they are terminally anthropocentric. The point of the film is that we need to achieve fewer humans, and this makes the anthropocentrists rabidly angry.

Moore makes an excellent point: creating solar panels and wind farms requires fossil fuels. Doing so in such a way as to accommodate perpetual growth is unsustainable.

We need to prune the human species to a sustainable level and keep it there.

We need forced sterilization, now. We need to limit waste and useless economic activity, now. Or else we will become extinct.

COVID-19 is clear and unequivocal evidence that population density has reached unsustainable levels. We are looking at The Great Filter.

We can have innovation, technical progress, and a good life. But we can only do that on a smaller scale.
